We can't predict for long term but for 2 to 3 years bit coin will be used as the medium of exchange of goods and services. In coming future btc will have the highest value of all currency. If I see it as 10 years from now than it can be the currency of some country as dollar.
The good feedbacks and bad reaction from the people who uses bitcoin helps bitcoin to know what to face in the near future, in every year they encountered different feedbacks. I think 10 years from now bitcoin will be one of the best crypto currency because of the learnings from the past years and thats what you call experience.
